Your question is a little vague, so answering is difficult. You could first start by explaining your setup and why you are looking at race gas. Also, which race gas are you referring to - all are not created equal.
Race gas (unleaded) is not harmful. Be aware that you can/will likely lose power if you do not have a proper tune for it. Just adding race gas to a car does not make it faster.
Race gas (leaded) will shorten the life of o2 sensors and damage catalytic converters. Again, a tune is necessary to take advantage of the added octane.
Osiris has map switching so you could put a "racegas" tune on map 2 or 3. One of the biggest difficulties with racegas in a Z/G is the gas tank. It is not simple to completely drain both tanks and exchange for a different fuel, so you often end up with a diluted mix when switching.

From what I have read I thought the z/g's were limited on adding timing in the mid, with tuning on 93 oct N?A. So if you cannot add more timing, race gas would be useless right?
FI can benefit due to them needing to remove lots of timing from the map to run boost. They can run race gas, and advance timing a couple degrees to gain some extra, right?

Race gas will benefit in many ways for track cars. Like Hal said though, for switching fuels out completely it's hard. If you tune it on full race gas (by completely draining) you need to spend the time to completely drain the non-race gas otherwise you can get a diluted mix of racegas and it won't match the tune (which is bad).
truthfully, race gas is quite costly and very time consuming if you are switching between street fuel and race fuel. It was a pain in the *** just switching out fuel for our bikes and they only have a 4 gallon tank that easily unbolts to drain it.
you need to decide is that extra few hp (and with only bolt ons we are talking just a couple hp) by tuning on race gas is worth all the trouble. A built engine with high compression would benefit more and be a little more worth the trouble.
